' to permit folding of the chart. It will be evident that the sections 2 may beequilateral if preferred, as shown best in Fig. 5.

While it will be apparent that each section may be extended to any desired length, I have in the principal figures indicated each as divided` into five main divisions,4 numbered 4, 5, 6, 7 and 8 respectively, the divisions being formed by the heavy arc-shaped lines 9, 9, in pairs, to provide spaces 10, l1, 12, 13 and 14, extendingl the full width, or

' transversely, of each of-the triangular sections or sectorsv2, wherein may be written reference or index numbers (see Figs. 1 and 2) for all names appearing in the records, making them easily indexed. Each of the main divisions is ruled with lighter arcshaped lines 15 to forni subdivisions 16, 17,

18, excepting 'only the main division 4, in which but one arc-shaped line is employed. Each of the main divisions except division 4 is divided by heavy radial lines 19 into what I shall for the purposes hereof term minor divisions 30, and each of 'these divided by lighter radial lines 31 for the reception of written data. The number of subdivisions 16, 17 and 18 increases toward the outer portion or base of the triangle, thus' practically utilizing the brace system, or system which is commonly used in tabulated pedigrees, without employing the great amount of space necessary and essential to such systems when on an ordinary undivided or` rectangular sheet.

Fixed by suitable eyelets on the face of the border 2O of one or more of the sections 2 are hotograph-holding strips 21 cut away ass own to provide pockets 22 for the reception of photogra hs. The border may be suitably 'Ornamente if; preferred.

The subdivisions 16, 17 are headed, in the first appearing or left hand division lwith the indicative words Names Time and Place and a portion of the spaces beloware left blank to be filled in with appropriate data concerning such. At the left of the Names column are printed the initial letters R, O and R indicating respectively, remarks, (or record,) occupation, and remarks, these being ai-bitrary. United by a brace z t the lower left hand portion of said column is the abbreviated indication S. or D.l of indicating as indexes.

son or daughter of. At the right of the brace are printed the abbreviations O, E, and M indicating respectively occupation, father, and inother.- The letters C midway of the Names column indicate church or creed.

The initial letters B D and M at the left of the Time column indicate respectively birth, death, and marriage. BI or Mo when elsewhere placed indicates mother, and F, father. The ancestral names are placed in main division 4. The ordinals, numerically arranged, placed in the spaces provided by the lines 9, serve In Figs. 1, 2, 3, and 4 I have shown a chart intended and purposed for the descending scale. In Figs. 5 and 6 I have shown a chart embodying the main features of the one just referred to, but especially designed for the ascending scale. Arlhe sections 2 are shown as right-angled triangles andare provided with reinforced apertures by which they are secured together similarly to the sections shown in the principal figures. In the modifications both arc-shaped and radial lines are shown, and the main and sub-divisions are formed in the same manner as in the others, but somewhat differently arranged.

The method of filling out the chart will be evident from an inspection of Fig. 2. In Fig. 1 I have shown by dotted diagonal lines the manner in which direct descent is indicated. To illustrate: Beginning at the name indexed by the numeral 50 in the outer portion of the division 14, the diagonal line running thence to the numeral 36 indicates that the person whose name appears on the last enumerated line is the father of the one enumerated on line 50. This line of descent is shown as being carried out on the lines indexed 22, 13, and 1, respectively, the latter being the progenitor.

Having thus described my invention, I claim as new and desire to secure by Letters Patent the following, to-witr 1. A' chart of the nature described comprising a plurality of isos'celes triangular sections, each suitably ruled with arciform and radial lines, the adjacent ends of all of the several sections but two flexibly united to those at each side thereof, and one edge of each of said two sections united to the adjacent section, whereby the several sections may be folded one on top of another, said sections forming an annular body when opened. but not adapted to wipe over each other in either opening or closing.

2. A chart of the character described comprising a plurality of isosceles triangular sections, the adjacent edges of all but two of said sections flexibly united to those at; the sides thereof, and one edge of each of said two sections similarly united to the adjacent intacte sect-ion, whereby the several sections may -be folded one on top of another and into compact body, but not adapted to Wipe over each other, said sections forming an annular body when opened. v

3. A chart of the character described com prising a plurality of appropriately ruled triangular sections, the adjacent edges l of each thereof provided with apertures, eyelets reinforcing said apertures, and means for flexibly connecting each adjacent pair of eyelets, said sections forming an annular body `when opened, and adapted to be folded one on top of another, but not to Wipe over l each other, to form a compact body.

A. chart of the character described comprising a plurality of appropriately ruled .riangular sections, the'apeXes of which tri-n angles have a common center, the adjacent edges of each of said sections provided with apertures, eyelets reinforcing said apertures and means :for unit-ing each adjacent pair of eyelets, said sections forming an annular body when opened1 and adapted to be folded one on'top of another, but not to Wipe over each other, to form a compact body.

5. in a chart of the character described, a plurality of triangular sections having a common apex, said sections forming a circular member when open, and means for flexibly connecting said sections whereby they are adapted to be disposed One on top of another, each of said sections being divided into divisions of a number of concentric arcs which forni concentric circles when the chart is open, and radial lines cutting said divisions, the number of said radial lines increasing toward the bases of the trianglb lar sections.

G. A circular chart divided radially into a plurality of independent triangular sections lhaving a common apex, and means for flexibly connecting said independent sections whereby said sections may be folded one above another into a compact triangular body.

7. A chart comprising a plurality of independent triangular sections having a com mon apexy said sections forming a circular body when opened, each of said sections divided into divisions by a number of concen u tric arcs, each of said divisions being cut by radial lines forming sub-divisions, the number of said sub-divisions increasing toward the bases of the triangular sections, a border having apertures therein corresponding in number and position to the adjacentsub divisions, said apertures adapted to receive photographs, and means for flexibly connecting said triangular sections, whereby they may be folded one on top of another into a triangular body.

In witness whereof I hereunto affix my signature at Chicago, in the county of Coolt and State ofl'llinois, this 22 day of Jan. 1912. t
